bug: Batch extract runs into TypeError: Object of type is not JSON serializable

[BuzzCutNorman]

Here are all the types that I currently know are running into this issue when the tap is generating batch messages.

• Decimal
• datetime
• date
• time

I think the best path is to overload the default JSON encoder used in the json.dump portion of get_batches. I found these links that have been helpful.

• https://docs.python.org/3/library/json.html#json.JSONEncoder
• https://sebhastian.com/python-object-of-type-int64-is-not-json-serializable/

I found that time is not a type that to_jsonschema_type() handles. I will add support for time in the PR assocaited with this issue.

I found some error with decimal columns. I will be placing a fix for this in the PR associated with this issue.
